3 years agobroadcom/compiler: always restart ldvary pipelining when scheduling ldvary

broadcom/compiler: always restart ldvary pipelining when scheduling ldvary

When we were only able to pipeline smooth varyings, if we had to disable
ldvary pipelining in the middle of a sequence it would stay disabled for
the rest of the program, to prevent us from prioritizing scheduling of
ldvary instructions that we would not be able to pipeline effectively.
Now that we can pipeline all ldvary sequences we can change this.

This change re-enables ldvary pipelining upon finding the next
ldvary in the program in the hopes that we can continue pipelining
succesfully. To do this, we track the number of ldvary instructions we
emitted so far and compare that to the number of inputs in the fragment
shader we are scheduling. This also allows us to simplify our ldvary
tracking at nir to vir time, since that is all now handled in the QPU

3 years agobroadcom/compiler: be more aggressive skipping unifa writes
Iago Toral Quiroga [Tue, 2 Mar 2021 12:05:09 +0000 (13:05 +0100)]
broadcom/compiler: be more aggressive skipping unifa writes

We had an optimization in place to skip a unifa write if the address
happens to be right after the last ldunifa read address, but we can
take this further and update the unifa address by emitting ldunifa
instructions if needed to skip a unifa write that is close enough.
This is because a unifa write involves 4 cycles: 1 for the write
and 3 delay slots before we can emit the first ldunifa.

So if we have code like this:

unifa addr + 0
ldunifa.r0
unifa addr + 12
ldunifa.r1

In practice we end up with QPU like this:

unifa addr + 0
nop
nop
nop
ldunifa.r0
unifa addr + 12
nop
nop
nop
ldunifa.r1

And with this patch we get:

unifa addr + 0
nop
nop
nop
ldunifa.r0  <--- reads offset 0
ldunifa.-   <--- reads offset 4
ldunifa.-   <--- reads offset 8
ldunifa.r1  <--- reads offset 12

Of course, QPU scheduling might find ways to fill the NOPs to some
extent and remove some of the gains, but generally speaking, this is
still usually a win.

Going by shader-db results, allowing the next unifa address to be up
to 12 bytes after the address resulting from the last ldunifa read
shows the best results:
